Aim: The study aimed to assess the effect of PNF techniques forward head posture (FHP) in patients suffering from Parkinson__ampersandsignrsquo;s disease. Material and Methods: This is a randomized controlled trial study. 40 subjects of forwarding head posture (FHP) with Parkin son__ampersandsignrsquo;s disease with craniovertebral angle (CVA) measured less than or equal to 500 and subjects were randomized in two groups: groups A experimental (N=20) __ampersandsignamp; group B control (N=20). The intervention group performed forward head posture corrective exercise in the form of PNF stretching exercise. The craniovertebral angle was measured before and after thrice in a week for 2 weeks exercise program. Result: After 2 weeks, a significant increase was observed in the intervention group regarding the mean of CVA (p__ampersandsignlt;0.001). When we compared the mean difference of outcome variable of both groups, CVA increased significantly after 2 weeks (MD= 2.63; 95% CI -2.16 to -1.13; t38= -6.50; p__ampersandsignlt;0.001). Conclusion: The current study showed that PNF stretching is a more effective treatment and could significantly improve the CVA angle in forwarding head posture. The results of the study suggest that PNF stretching is more effective in FHP. PNF stretching also increases the cervical range of motion, improve muscle elasticity.
